Introduction

Welcome to the online resource for owners and admirers of the Saab 9-3 Viggen sports car!

This page might also be of interest to those interested in performance tuning of regular Saab 9-3 cars (on which the Viggen is based), Saab 900-II cars
(on which the 9-3 is based) and Saab 9-5 cars (on which the Viggen´s B235R engine is based).

I try to follow a scientific approach to performance tuning: I perform a dyno-test for every step of engine tuning I apply, and I test every modification
to the car on the race track.
I hope you can take advantage of my experiences gained in this process.
